Description
technical field [0001] The invention relates to the field of electronic energy saving, in particular to a beam-excited constant-current pulse liferaft energy-saving system based on gate drive. Background technique [0002] At present, whether it is an air crash or a sea disaster, life rafts are all indispensable life-saving equipment. And just must save as the electric energy of life raft, to ensure that the flashing warning light that is used for sending distress signal can work more persistently. In the past, life raft lights used seawater batteries to ignite two small electric beads of 3V and 0.25A, one of which was used as a distress signal, and the other was used as lighting inside the raft. However, to maintain 8 hours of lighting and emergency power, at least seawater batteries are required to have a capacity of 4Ah (Ampere hours). Due to the relatively large volume of seawater batteries and the high energy consumption of life raft lights, this not only leads to the...
